To all whom t may cancer/n.:

Be it known that I, EDWIN a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pernsylvania, have inf use ing'Machine, of which the following is a specification.

The` principal object of the present inventionis to Lprovide a simple, reliable, and efcient tube making machine the parts of which can be readily and quickly adjusted to change the pitch of the winding without possibility or danger of their getting 4out of adjust-ment in respect to each other.

Another object of the invention is to simplify the applicationof driving power to the adjustable parts of the machine, and another object of the invention,r is to improve and simplify the combination and arrangement of the various-parts of the machine.

The invention will be claimed at the end hereof, but will be first described in connection with the embodiment of it selected for illustration in the accompanying drawings, in which-- Figure 1, is a top or plan view of'a machine embodying features of the invention. Fig. 2, is a transverse sectional view, taken on the line 2 2 of Fig. 1, lookingin the direction of the arrows. Fig. 3, isa side view, partly in cent-ral section, with portions of the machine remo-ved, and Fig. 4, is an end view, partly in section, of the machine,

equipped with a modification of the invention.`

. In the drawings, 1 is a bed or table provided `with a head 2, which carries the fixed spindle or shaft 3, on which the tube strips 4 are spirally wound. Pivotally connected with the table and shown as mounted upon a pad thereon is a platform'. The platform is centrally pivoted 'and its pivotal point is in line with the center of the fixed shaft or spindle 3. Tothe pivot 6 of this platform is secured a worm-wheel 7, which can be turned by means of a conveniently located hand-wheel 8, through the intervention of a worm-shaft and worm 9.

The platform 5, consists of a centrally arranged base portion 10 upon which is mount ed the electric motor 1l and of upwardly and outwardly extending arms 12 and 13, so that when 4the platform is turned, the motor J. SoHonr'rLn,

ful Tube-Makand all parts carried by the platform are moved. The wiresI or leads not shown which supply current to the motor may be `suticiently slack for accommodating this movement of the motor. The pulleys 14, 15, 16 and 17, for the wrapping belts 18 and 19 are revolubly mounted in suitable journals, carried by the arms 12 and 13, so that when the .platform is turned about its central pivot all of the pulleys are moved and vthe angle of the direction of travel of qthe belts with respect to the fixed spindle 3, is changed, the change is not great, but it is sufcient for the purpose. The pivots for the pulleys 15 and 16 are adjustable by identical means, of which one only need be described. The pivot of the pulley 16 is carried by a block 20, slidable in the arm of the plat-form and its position is controlled by the set screw 21 which is operated by the hand-wheel 22. By means of the hand-wheel 22, the belts may be tightened or slackened, for example, to adjust them to tubes of different sizes as well as for other purposes.

The means for driving the belts 18 and 19 are duplicates of each other and therefore but one will be described. Before doing so, it may be said that each end of the motor shaft is used for driving one set of these means. There is a counter-shaft 23 journaled in the arm of the platform and this counter-shaft is driven by a sprocket chain 24' and its sprocket wheels, of which one, 25, is on the motor shaft and the other, 26, is on the counter-shaft. The counter-shaft is provided with a pair of sprocket wheels 27 and 28. The sprocket wheel 28 is geared to a pulley shaft by a sprocket chain 29 and sprocket wheel 30, and the sprocket wheel 27 is geared to a pulley shaft by the sprocket chain 31 and sprocket wheel 32. A belt tightener 33, is employed in connection with the last named sprocket chain to keep it properly' adjusted when the pulley which it drives is shifted by means of the wheel 22. The si7`e of the various sprocket wheels is designed'wit-h regard to the speed of the motor and to any speed reduction that may be required in driving the belts.

In the modification shown in Fig. 4, the chains 31 and 29 are dispensed with and the belts 18a and 19a are passed around their pulleys 14a and 16a and 15- and 17a, which pulleys run loose. The belts are then passed over pulleys Y) on the counter-shafts 23 and then over idle pulley c, so that the belts are driven from the pulleys -b on the countershafts. l

It is evident that theanecessary adjustments inthe pitch of winding can be' made loosened by turning the hand-wheel 22,

. without danger of disarranging any of the other parts. The flexibility of the leads or conductors which supply the motor with power affords the motor the slight move-o ment necessary when the pitch is changed by turning the platform 5.

What I claim is: l 1. A tjlbe making machine comprising a frame having a fixed winding spindle, a platform centrally pivoted tothe frame and having lateral rigid arms provided with immovable counter-shaft bearings, an elec tric motor carried by and disposed centrally of the platform, a counter-shaft in the `immovable bearings on each arm, connections from the 4motor to each counter-shaft for driving it, pairs of pulleys for winding belts carried by the arms. and whereof one pulley in each pair is adjustable in respect to the arm which carries it, and winding belts driven from the counter-shafts, substantially as described.

2. A tube making machine comprising ay frame having a fixed winding spindle, a platform centrally pivoted to the frame and noemer Ahaving lateral rigid arms, an electric motor carried by and disposed' centrally of the platform, winding belts, pairs of pulleys for the winding' belts carried by the arms and whereof one pulley in each pair is adjustable in respect to the arm which carries it, j

a counter-shaft on each arm, connections from the motor to each counter-shaft for` form, winding belts, pairs of pulleys for the winding belts carried bythe arms and whereof one pulley in each pair is adjustable in respect to the arm which carries it, a counter-shaft on each arm, connections from the motor to each counter-shaft for driving it, connections from each countershaft to the pulleys for driving them and' whereof one connection includes a belt tightener, and a wormy and worm-wheel and their complemental hand-wheel for turning the platform and parts carried thereby, substantially as described.

l In testimony whereof I have hereunto signedmy name.
